How to Replace the Wheel Bearings on a Dodge Ram 1500

Wheel bearings support the truck's weight and allow the wheel to turn freely. Every Dodge has front and rear wheel bearings that each support close to 850 pounds.

  • Loosen the lug nuts and the axle nut before raising the vehicle. Raise the vehicle with a jack and secure it on a jack stand. Remove the lug nuts and the wheel. Remove the axle nut.

  • Remove the brake caliper by unscrewing the brake bracket mounting bolts found at the top and bottom of the caliper. Do not let the caliper dangle because it could damage the brake line. Support it on a block or zip-tie it so that it is secure.

  • Remove the rotor and the hub nut with the 36mm socket. Turn the steering wheel to gain access to the hub mounting bolts, and remove them with a socket wrench. You will need to turn the steering wheel in both directions to gain access to all of the mounting bolts.

  • Remove the ABS sensor wire, and use a screwdriver to pry the hub loose and remove it. You might need to use a gear puller to separate the hub from the steering knuckle.

  • Apply anti-seize compound to the new hub where it will fit tightly against the steering knuckle. Also apply anti-seize compound to the splines on the axle. Tighten the hub bolts to secure the new hub and then tighten the hub nut.

  • Replace the rotor and brake caliper on the rotor. You might need to push the caliper piston in with a C-clamp first to get it to fit back over the rotor. Reconnect the ABS line.

  • Replace the wheel and tighten the lug nuts as much as possible. Lower the vehicle to the ground and finish tightening the lug nuts and the axle nut with the impact wrench. If you had to push the caliper piston with a C-clamp, pump the brakes to restore hydraulic pressure.
